MACHINE FOR NECKING VIALS 0R BOTTLES.

Application filed September 19, 19242.y Serial No. 589,092.

T0 all whom t may concern.'

Be it known that I, DAvm B. KING, a

citizen of the United States, residing at Mill- 4 p .and illustrating features of the invention,

ville, in the county of Cumberland and State of New Jersey, have invented a new and useful Improvement in Machines for Necking Vials or Bottles, of which the following is a specification.

Vials or bottles are made from pieces of glass tubingwhich is supposed to be of substantially the same diameter, butl in fact glass tubing rated as of the same diameter varies in size. The mechanism which forms the necks of such vials or bottles operates upon the end of a tube whilst the same is inv` rotation so that it is important that the tube be properly centered in respect to that mechanism because otherwise the necks both The principal object of the present inven-,

tion is to provide mechanism for automatically presenting the rotating tubes properly to or co-aXially with the corkage forming mechanlsm, even though the tubes vary in diameter, whilst nominally of the same size.

To this and other desirable ends, the invention may be said generally to comprise the combination with the corkage or neck forming mechanism, of a scissor-like support for the rotating tube by which 'it is axially alignedwvith` such forming mechanism, and means responsive to the diameter of and actuated by the rotating tube and adapted to position said scissor-like support.

The invention further comprises the improvements to be presently described and finally claimed. In the following description, reference will be made to the accompanying drawings forming part hereof and in which- Y Figure lis a view, partly in section, illustrating mechanism embodying features of the invention and showing the same in application to a machine for making the corkage or necks of vials or bottles.

Fig. 2 is a sectional view taken on the line 2 2 of Figure 1.

.Referring to the drawings, e is a plug adapted to enter the end of a tube and g is a ianged roller, the plug and roller co-operating to form the neck on the end of the bot- ,tle or rotating tube a, the plug forming the fcorkage. f is a rotatable abutmentfor the opposite end of the tube.

d `is a resilient, beveled roller usually of rubber or the like, and it serves to rotate the tube t and also to position the tube against the abutment. The described parts are usual provisions of a machine for making vials or bottles and in and of themselves they form' no part of the present invention. The two arms both pivoted at j and having at one of their ends rollers 0 on shafts h, and at the other of their ends rollers Z, constitute ascissor-like support for the rotating tube a, Fig. 5. If the upper ends of these arms z' are. made to recede from each other it is evidentv that the axis of the tube a is lowered and that if the upper ends of these arms i are made to approach each other the axis of the tube a is elevated to a higher level. By positioning the arms i in the manner described-it is possible to bring the axis of the tube t into alignment with the axis of the plug e, and the fact that the roller al is resilient permits of such adjustment, whilst the roller d is rotating the tube n, upon the supporting rollers c, of which four are shown. The arms z' are positioned in response to the diameter of each tube a that is being worked upon. For that purpose there is provided a frame o slidably mounted in the fixed base 7c and equipped with a grooved cam m, operating upon the rollers Z, and with rollers g that ride on the tube a. There is a spring u interposed between the frame o and the base lc, and it tends to shift the frame downward, balancing the thrust of the roller d and leaving the rollers q free to ride in contact with the tube a. The positively driven cam y mounted-on the shaft operates a follower lu pressed by spring fw, and the movement of the shaft w is so timed that the follower v ur -oFFici-zf i which the cam m i's mounted.

The -rollers are shown as mounted upon a plate p having sliding adjustment with a part of the frame o and held in place by a clamping screw fr. The purpose of this adjustment is to accommodate the device to tubes rated as of dierent-diameters 'and not to such variationsl in diameter as occur in tubes rated as of the same diameter. The frame o is slotted as indicated at s for the accommodation of the abutment f, so that the frame can rise and fall in respect to the abutment.

'Ihe lower portion' t of the slotted part s may be arranged to serve as a limit stop in connection with the base la, Figures 2 and 4. x

The mode of o eration ofthe described mechanism may e explained as follows: The high part of the cam y operating upon the follower fv lifts the frame o and in that wa raisesI the rollers g and spreads the rol vers c apart thus' affording room between the rollers through which the tube a can be fed onto the rollers c and under the rollers q. 'Ihen the cam y causes the follower 'v Ato release the frame o which descends until its-downward movement is limited by the riding of the rollers g on the top of the tube a. rIhis positioning of the frame tacting through the cam m determines the distance apart of the centers of the rollers c,

and the combined operation brings the axis of the tube a into line with the axis of the plu e, in the case of tubes a, which diner 1n iameter, although supposed to be univform in that regard. 'Ihe operation of the neck forming mechanism e and g and of the burner or heater B is well understood and needs no articular description.

It will e obvious to those 'skilled in the art to which the invention relatesthat modiications ma be made in details of construction an arrangement of parts withoutl departing from the spirit of the invention, which is not limited as to those matters or otherwise than as the prior art and the `appended claims may require.
